Southern Cross


One night at the camp site the sky was clear and the stars were clean and sharp, even for an automatic camera to catch. We have not been able to see the Southern Cross easily in Summer because it is upside-down and therefore close to the horizon. It took a clear night and an unobstructed vista to locate it. In the Winter sky it is upright as seen on our flag, not so in Summer.


Not everybody is aware that the 'down' line (direction) of the cross and a perpendicular line drawn from the nearby 'Pointers' intersect at the South Celestial Pole. This is an important rule for navigation in the south sees.


This last picture is looking north, looking at some of the Zodiac constellations, except that they are all upside down, and we give them different names... like the Saucepan. Can you see it?
